Description

The present invention relates to an ultrasonic diagnostic apparatus having a multi-plane scan function that is a function of displaying a multi-fault plane.

Conventionally, some ultrasonic diagnostic imaging apparatuses for observing in-vivo images have a multi-plane scanning function. In such an ultrasonic diagnostic apparatus, a two-dimensional array probe or a mechanical oscillating probe that can transmit an ultrasonic beam in any direction is used. With such a probe, a plurality of different subject sections can be scanned substantially simultaneously. Based on such scanning, a plurality of ultrasonic images representing different subject cross sections can be displayed side by side. Such a function is called a multi-plane scan function or a multi-display function. A doctor can observe the displayed image to make a three-dimensional diagnosis.

In a conventional ultrasonic diagnostic imaging apparatus related to the multi-plane scan function and the multi-display function, it is possible to perform various changes in image quality conditions and display conditions. Here, the image quality conditions are ultrasonic output, ultrasonic radiation density, reception sensitivity, signal processing method, and the like, and the display conditions are display size and display scanning line density in the display device. These image quality conditions and display conditions are set in the same manner in any of the ultrasonic images displayed side by side, and display with the same image quality and the same display form is performed.

By the way, the spatial range that humans can watch is not so wide. Therefore, even if a plurality of images are displayed, only one image can be observed in detail. In this case, the other image to be watched has a meaning as a pilot image for three-dimensionally grasping the imaging region, and therefore often does not require detailed observation.

However, in a conventional ultrasonic diagnostic apparatus having a multi-plane scan function and a multi-display function, when one of a plurality of ultrasonic images displayed at the same time is to be observed in detail, the image quality of both displayed simultaneously, There was nothing else than adjusting the display conditions. For example, when the ultrasonic radiation density is increased and the display magnification is further increased, the same setting change is performed on the other image. In such a case, although the other image is not noticed, the frame rate of the image to be observed is reduced due to the increase in the radiation density of the other image. Further, although the display area of the monitor is limited, the upper limit of the display magnification of the image to be observed is lowered due to the increase in the display magnification of the other image. That is, the image quality and display area of the image to be observed are limited due to the linkage between the image quality condition and the display condition of the image that is not the observation target.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an ultrasonic diagnostic apparatus according to the present invention. As shown in FIG. 1, the ultrasonic diagnostic imaging apparatus 10 of the present embodiment includes a control unit 11, a transmission / reception unit 12, a signal processing unit 13, a two-dimensional array type or biplane type ultrasonic probe 14, and , A display unit 15 such as a monitor, and an operation unit input unit 16 using a keyboard, a trackball, or a touch command screen (hereinafter abbreviated as TCS). Further, when referring to an external signal such as an electrocardiogram signal, a biometric information input unit 17 which is an external signal unit is added to the configuration.

Further, the control unit 11 includes an operation unit input unit 16 and a biological information input unit 17.
A CPU control unit 111 that performs computer processing to which the computer is connected, a control information program unit 112 that stores a computer processing program, and a control unit database that stores in advance data relating to the configuration of various multi-display display modes performed by the present embodiment 113.

The transmission / reception unit 12 also includes an ultrasonic signal transmission circuit 121 for driving the ultrasonic probe 14 placed in contact with the subject 18 and a reception circuit 122 for receiving and processing a reflected ultrasonic signal from the body of the subject 18. And an ultrasonic transmission / reception control unit 123 for controlling the transmission circuit 121 and the reception circuit 122 by a control signal output from the CPU control unit 111 and transmission / reception control data of a control pattern stored in the control unit database 113 temporarily. And a transmission / reception control data memory 124 to be held.

The signal processing unit 13 includes a signal processing circuit 131 that is processed by the receiving circuit 122 and receives a received signal, an image control data memory 134 that temporarily stores control data stored in the control unit database 113, and a CPU control unit 111. And the control data from the image control data memory 134, the signal processing control unit 133 that outputs a signal processing control signal to the signal processing circuit 131, and the image signal output from the signal processing circuit 131 for each image. An image screen generation circuit 132 configured by control data from the image control data memory 134 is provided on the multi-image display screen in the display unit 15.

In the control unit database 113, control data related to the display form is stored in advance for each set of a plurality of ultrasonic image configurations that the multi-display is simultaneously displayed on the display unit 15 in the present embodiment. This control data is set for each number (n) of ultrasonic images displayed on the display screen of the display unit 15. For example, it is set for each of the case of two-image display, the case of four-image display, etc. Further, a plurality of display screen forms are set for the case where the number of display images is a certain value m. For example, in the case of a two-screen display, it may be control data for displaying two images of the same size, or control data for displaying one smaller and the other larger. That is, if the number of display screen forms is m, this control data can be classified as a file Fnm. For example, the contents of the file F20 are schematically shown in FIG. The file F20 is control data for displaying in the 0th display screen form in the case of two-screen display. If two images displayed at the same time are an A image and a B image, data is set for each of them. Further, data for each image is classified into transmission / reception control data and image display control data. The transmission / reception control data is, for example, data related to ultrasonic drive voltage, scanning line density, reception gain, pulse gate width, beam delay data, scan order, and the image display control data includes display luminance range, display size, color / Monochrome display, still image / video display, etc. Here, for convenience, the o-th data in the display screen mode n for the X image is represented as TXno. Assume that the default setting when selecting the number of display images in the ultrasonic diagnostic imaging apparatus of the present embodiment is based on the file Fn0 (FIG. 3B is a file F20 in the example of a two-image screen). The file Fn0 has the same display form as the conventional multi-display display form, and is control data for displaying a plurality of images under the same conditions.

The operation and operation of the configuration of the ultrasonic diagnostic imaging apparatus 10 of the present embodiment shown in FIG. 1 will be described using the flowchart of the processing procedure shown in FIG. In the following description, the number of screens simultaneously displayed on the display unit is determined by, for example, a two-dimensional array ultrasonic probe or a biplane ultrasonic probe that scans different slice (tomographic) planes in order to avoid complexity. A case will be described in which a two-image screen including a display screen in which an A image and a B image are arranged on the left and right is described.

Furthermore, the number of display form patterns of the A image and the B image stored in advance in the control unit database 113 of the ultrasonic diagnostic imaging apparatus 10 of the present embodiment is (m + 1) sets from F20 to F2m.
Therefore, in addition to the screen pattern of the file F20 in which both the A image and the B image are displayed on the same condition, for example, when the A image and the B image have different ultrasonic scan beam densities, display magnifications, or display sizes, Alternatively, the control files F21 to F2n are stored when one of both color display images is monochrome display or when one of the moving image displays is a freeze (still) image display.

First, the ultrasonic diagnostic imaging apparatus 10 according to the present embodiment is activated, and a display form for two-screen simultaneous display is selected by a predetermined operation. Then, in step S11 shown in FIG. 2, the A image and the B image on the display screen are displayed under exactly the same transmission / reception conditions and image display conditions. This is a two-image display similar to the conventional multi-display type ultrasonic diagnostic imaging apparatus. In this conventional display mode, the vicinity of the target region of the subject is searched, and the target diagnosis target is captured in the ultrasound image.

Next, further detailed observation and diagnosis are performed on the captured target portion. In step S12, the touch command screen device (TCS) of the operation unit input unit 16 of the present embodiment.
) By operating an input instruction device such as a mouse or a trackball, an instruction is made to input an ultrasonic image display form suitable for a desired diagnostic purpose.

By the instruction input in step S12, one of the files Fnm stored in the control unit database 113 is determined in step S13.

The referenced transmission / reception control data is temporarily set and stored in the transmission / reception control data memory 124 of the transmission / reception unit 12 in step S15. Similarly, the signal processing control data is temporarily set and stored in the image control data memory 134 of the signal processing unit 13 in step S16. A part of the control data recorded in the control file Fnm searched in step S13 is used as control parameter calculation calculation data in step S14. The resulting data is stored in the transmission / reception control data memory 124 or the image control data memory 134.
Are also temporarily set and saved.

Based on the control data temporarily set and stored in the transmission / reception control data memory 124 in step S15, the transmission circuit 121 and the reception circuit 122 are operated in step S17, and transmission / reception of ultrasonic signals to the subject 18 is performed. Done. In step S18, the receiving circuit 12
2 is input to the signal processing circuit 131. Based on the image display control data temporarily set and stored in the image control data memory 134 in the previous step S16, the image display pixel data is obtained. The signal processing circuit 131 processes the image signal to be generated.

The processing result of the signal processing circuit 131 is input to the image screen generation circuit 132, and the display screen is configured. This display screen configuration is performed based on the control data temporarily stored in the image control data memory 134 in step S19. In step S20, the A image,
The pixel data of the B image is mapped to the screen frame memory provided in the image screen generation circuit 132 according to the setting in step S19.

In step S21, the screen frame memory data of the image screen generation circuit 132 is read to the display unit 15 for each frame. As a result, both the A image and the B image having different ultrasonic transmission / reception settings and image display settings are displayed on the display screen of the display unit 15.

Further, in step S22, it is determined whether or not to change the ultrasonic transmission / reception setting and the image display setting for the A image and the B image on the display screen of the display unit 15. If you want to change it,
When the instruction is input, the process returns to step S12. If there is no change instruction, step S1
The control data of the file Fnm searched in 3 is maintained. Thereby, step S1
2, the display format is displayed in the previous display mode until an instruction to change the display type is given.

Although two images A and B are described, a general three-image or more multi-image screen includes at least one image group of a plurality of images displayed in a predetermined screen display form. If the remaining image group is replaced with the B image for the A image, the same process can be performed when there are a plurality of images of interest.

In the present embodiment, the above-described processing procedure is stored in advance in the control information program unit 112 as a computer program, and this program is executed by the CPU control unit 111 so that the ultrasonic signal processing is performed and specified. The display may be executed in the display form.

Next, an example of a display form of a plurality of images displayed on the display unit 15 in the present embodiment will be described with reference to FIGS. Here, in the case of displaying two images, the details of the processing of steps S12 to S19 in each display mode will be described.

(Display Example 1)
FIG. 4 schematically shows how the display form changes according to this embodiment. In the first embodiment, as shown in a) of the figure, first, like the display screen of the conventional multi-display, two images of the A image 41 and the B image 42 of different slices (tomographic planes) are displayed in the same manner. Displayed by condition.

In step S12, the operation unit input unit 16 is mostly a TCS (touch command screen), or an instruction icon that displays only one selected image as a moving image displayed on the operation display screen, for example, “select right side”. Click (not shown).

Since this “select the right side” icon corresponds to the file F2a stored in the control unit database 113, this file is searched as setting data in step S13.

The control data recorded in the searched file F2a will be described below. Image A
In the transmission / reception control data for TA, for each parameter k = 1 to K, TAak
TBak is set to scan only the A image. That is, TAak is set to be suitable for scanning only the A image, and TBbk is set not to scan the B image. In GAak, display conditions along TAak are set, and GBa
k is set so that the image is not updated and the frozen state is set.
By this processing, each of these image data is finally mapped by the image screen generation circuit 132. Then, the screen data for each frame is output to the display unit 15. This
As shown in FIG. 4B), the right image 46 is a real-time image of a moving image, and the left side is displayed on the monitor 5 in a display form of a screen 47 that displays other slices as still images.

According to display mode example 1 of the present embodiment, without waiting for the scan for the B image, A
Since the scan for the image only needs to be repeated, the frame rate of the A image is doubled.
As a result, the movement of the A image can be observed with a smooth display, diagnosis is easy, and the accuracy can be improved.

(Display type embodiment 2)
FIG. 5 schematically shows a changed display form according to the present embodiment. In the second embodiment, as shown in a) of the figure, first, similarly to the display screen of the conventional multi-display, two images of the A image 51 and the B image 52 of different slices (tomographic planes) are the same condition. Is displayed.

In step S12, an instruction icon (not shown) displayed on the TCS or the operation display screen, for example, “display right side in detail” is clicked.

The “display right side in detail” icon corresponds to the file F2b stored in the control unit database 113. In this file F2b, for example, the display frame rate of the item i of the image display control data is set such that GA0i = GAbi, GB0i = GBbi. That is, the same condition is maintained even after the display form is changed. On the other hand, for example, h of transmission / reception control data
The scan rate of the term is set as follows for each of the A image and the B image. First, as described above, the A image and the B image are not distinguished in the initial state.
A0h = TB0h. However, in the changed file F2b (not shown), the image A5
6. For image B57, set so that TAbh> TBbh.

These control data are transferred to the control units 123 and 133 in steps S15 and S16.
Is input. Thereby, the frame rate of the A and B images is not changed, the scanning line density of the A image 56 can be increased, and the B image is continuously scanned.

By this processing, each of these image data is finally mapped by the image screen generation circuit 132, and the screen data for each frame is output to the display unit 15, as shown in FIG. Both images with different scan rates for the A image 56 with an increased scanning line density and the B image 57 with a lower scanning line density are displayed on a monitor in a display form in which a real time (moving image) image is displayed.

According to the display mode example 2 of the present embodiment, the B image 57 of a slice (tomographic plane) different from the A image 56 with an increased scanning line density is a dynamic three-dimensional display of both images. It is preferable for observation, and the display of one of the specified A images, for example, is displayed with a higher density scan than the other B image, and the motion of the moving image can be observed with a smoother display, enabling detailed diagnosis. The accuracy can be increased.

Here, as an example, a case has been described in which the scanning line densities of the A image and the B image are changed to keep the frame rate constant, but the present invention is not limited to this. The scanning line density may be the same by changing the frame rate, or both the frame rate and the scanning line density of one image may be improved.

When one frame rate is improved, the scan order for each cross section is, for example, as follows. When the frame rate of the A image is improved, the control data is set so that the B image is scanned only once while the A image is scanned twice. For example, it is possible to scan the entire A image every half of scanning the B image. Further, when the scanning line density is the same, a setting is made such that one scanning line of the B image is transmitted and received every time two scanning lines of the A image are transmitted and received.

Furthermore, although the above description does not mention the method of setting the scanning line density after changing the A image and the B image, several sets of numerical values of the scanning line density that are considered to be easy to use are set in advance. It is good also as making it select. Also, there may be means for appropriately inputting numerical values, and different scanning line densities may be set for the A image and the B image accordingly.

(Display Example 3)
FIG. 6 schematically shows a change of the display mode embodiment 3. In this display mode, as shown in a) of the figure, first, as in the conventional multi-display display screen, two images of the A image 61 and the B image 62 of different slices (tomographic planes) are the same. Is displayed.

Next, in step S12, the instruction icon displayed on the TCS or the operation display screen, for example, “display right side larger” is clicked.

The display mode activated by the “display large right side” icon is that the desired ultrasonic image is enlarged to a larger display size (number of occupied rasters), the scanning line density is increased, and the A image 6
6 and the other screen is displayed in the form of a B image 67 with a reduced display size and a reduced scanning line density. In step S13, for example, the file F2c of the control data is retrieved.

The file F2c includes TAch and TBc which are scanning line density data of transmission / reception control data.
h, and display size data GAci and GBci of the image display control data are included. Here, TAch> TBch and GAci> GBci.

Transmission and reception of ultrasonic waves and generation of the image screen 65 are performed by the control data set in this way. As a result, as shown in FIG. 6B, for example, the right A image 66 is displayed larger than the other B image 67 on the display device 15, and the scanning line density is also increased. Both images are displayed as real-time moving images.

According to this display mode of the present embodiment, if a target to be focused on in diagnosis is displayed on the A image, detailed observation and advanced diagnosis can be performed easily and quickly.

Here, as an example, the case where the scanning line densities of the A image and the B image are made different has been described, but the present invention is not limited to this. Both the frame rate and scanning line density of one image may be improved.

Further, the above description does not mention the method for setting the scanning line density and display size after changing the A image and the B image. It is also possible to set some items and select them. Further, it may have means for appropriately inputting numerical values, and according to this, different scanning line densities and display sizes may be set for the A image and the B image.

(Display Example 4)
FIG. 7 schematically illustrates how the display form changes according to the present embodiment. In this display mode embodiment 4, as shown in a) of the figure, first, the two images of the A image 71 and the B image 72 of different slices (tomographic planes) are the same as in the display screen of the conventional multi-display. It is displayed with the condition of.

Further, the display mode embodiment 4 includes a biological information input unit 17 which is an external signal unit for detecting a biological signal. This biological signal is any one of an electrocardiogram signal, a pulse wave signal, a respiratory signal, and the like. In the display mode embodiment 4 described here, an electrocardiogram (referred to as ECG) is detected, and in synchronism with this, the longitudinal section of the heart is set as the A image 71 on the right side and the cross section is displayed as the B72 image by the transesophageal biplane probe. As an example, description will be given.

In step 11 of starting image diagnosis by the ultrasonic image diagnostic apparatus 10 of the present embodiment, the image is displayed in the same display form as the conventional multi-display image display 70. That is, the ultrasonic transmission / reception conditions and signal processing conditions of the displayed A image 71 and B image 72 are the same conditions for both images, and as shown in FIG. The electrocardiogram waveform 73 is displayed in an image configuration 70 that is displayed superimposed on the lower side of the image.

In step S12, most of the operation unit input units 16 are displayed as TCS or an instruction icon (for example, “alternately changed”), which activates predetermined processing alternately in synchronization with an external input signal. Click (not shown).

Since this “alternate change” instruction icon corresponds to the file F2d stored in the control unit database 113, this file is searched as setting data in step S13.

And, for example, as shown in the display screen 75 in FIG.
The control data is set such that, for example, the scan line density is TAdh <TBdh and the display size is GAdi <GBdi so that the left B image 77 has a high scan density and raster density and the A image 76 is displayed coarsely. It is set to be. With this set value, during the period of one heartbeat, the display of the left B image 77 is displayed on the monitor of the display unit 15 more clearly than the right A image 76. For example, since the cross-section of the heart is clearly displayed in the B image 77,
It becomes easy to observe the contraction state and the volume of the ventricle.

During the observation of the clear display of the above B image, for example, the appearance of the next R wave 73r of the electrocardiogram waveform,
When the start of the next heartbeat is detected by a trigger signal from the biological information input unit 17, the A image data and the B image data in the transmission / reception control data memory 124 and the image control data memory 134 are replaced and rewritten. . That is, each control data memory 1
24 and 134, the data TBd1 to TBdk and the data GBd1 to GBd are included in the A image data portion.
k is set, and data TAd1 to TAdk and data GAd1 to GAd are set in the B image data portion.
dk is set respectively. Specifically, every time a trigger signal is input from the biometric information input unit 17, the folder “image B” is subfolded in the same manner as the lower folder “image A” of the setting data file F 2 d to be searched in step S 13. This is done by replacing or replacing the name. Thereafter, steps S14 to S18 are executed. If there is no input to cancel step S22 or change to another display mode, when step S18 ends, the display data of both images proceeds to the process of step S19. And again step S
Returning to 13, the control data of the control data memories 124 and 134 is maintained until the next trigger signal is input from the biological information input unit 17, and the display form is maintained. When the next trigger signal is input, the control data of the A / B images in the control data memories 124 and 134 are rewritten.

In this way, in the next period of the biological signal, the clear B image 77 is changed into the coarse raster B image 77.
The other image (A image 76 ′ in FIG. 7c in the explanation example) is clearly displayed on the display screen 75.
For example, in the A image 76 ′ indicating the longitudinal section of the heart, the opening / closing state of the valve or the like is displayed on the monitor and can be closely observed.

According to the display mode of the fourth embodiment described above, the ultrasonic images of different slices (tomographic planes) are changed by repeating the image transmission / reception and display conditions alternately for each periodic activity of the living body. In addition, it is possible to observe under clear and detailed image display conditions suitable for observation and diagnosis. In addition, the biological information is also superimposed on the screen and displayed on the monitor, and observation and diagnosis corresponding to the timing of the cycle can be performed in detail based on the clear A and B images.

Moreover, although the above-mentioned description demonstrated the case of the transesophageal biplane probe, it is not restricted to this. It goes without saying that such an operation can be performed even with a two-dimensional array ultrasonic probe for imaging by contact from outside the body. Even such a two-dimensional array ultrasonic probe is particularly effective when used for observing the heart.

Here, as an example, the case where the scanning line densities of the A image and the B image are made different has been described, but the present invention is not limited to this. Both the frame rate and scanning line density of one image may be improved.

Further, the above description does not mention the method for setting the scanning line density and display size after changing the A image and the B image. It is also possible to set some items and select them. Further, it may have means for appropriately inputting numerical values, and according to this, different scanning line densities and display sizes may be set for the A image and the B image.

Also, in any of the first to fourth display embodiments described above, it is possible to determine what type of probe is connected and automatically change it to a predetermined setting suitable for it.
